If a saved settings file is available from a web server, you can send email to others with a link such as http://genome-euro.ucsc.edu/cgi-bin/hgTracks?hgS_doLoadUrl=submit&hgS_loadUrlName=U where U is the URL of your settings file, e.g. http://www.mysite.edu/~me/mySession.txt . In this type of link, you can replace "hgSession" with "hgTracks" in order to proceed directly to the Genome Browser. For an example page using such links please see the Session Gallery.
